Back spasm, 1 day ago, and  no doctor can see me until Monday because of Christmas?

I litterally got out of my car and bent 3in to pick up seatbelt that did not retract, and bask freezed up.  I emmediately put heat, and then ice when I got home. heat for first 6 eeve hours, 20mins. an hour. Then ice 20mins, for the next 2 hours.  Took advil 2 twice, and 2 Aleeve once before going to bed last nigh and 2 about 9am this morning. Still in pain, can not stand up strait at all.  even with a pillow, sitting, the pain is a 3, when I stand and walk, its an 8.  What to do.  I have an upside down hang from ankles machine I can get on, but have to wait for family because I do not think I have the strength to pull myself back up right. And advice?
